“We’ll also be playing a few tracks off our last album and possibly even one or two tracks off our up-and-coming album,” Robin adds.

The band sometimes resurrect songs they haven’t played for a while and sometimes offer a few surprises, he explains, but the classics simply have to be there.

“The second we do ‘Red Red Wine’ and the audience sings it back at us like a football crowd, that’s a buzz that you can’t replace. I love playing songs that the audience want to hear.”

Robin is also eager to play on the same stage as Aswad once again.

“We’ve played with them before in the past but we haven’t seen them for a long time and we haven’t played with them for a long time, so I’ll be looking forward to that more than anything.”

“Aswad have always been a great live band,” he continues, explaining that the long-running group have a similar attitude to their concerts.

“They’re a great reggae band and they play dance music so it’s a party vibe and that’s the kind of thing I’m into too.”

Away from the stage, UB40 have been working on their new album, which should be out this year in conjunction with PledgeMusic.

So how’s that all progressing?

“Uh, slowly,” Robin laughs. “We’ve been working probably for the past two years on it now. We’re still a very hard working live band...so it’s whatever opportunity we have to get into the studio.”

Robin reckons that, in total, they’ve probably put in a few weeks of studio time during this period.

“But we’re getting near to completion,” he confirms. “I’m actually in the studio at the moment, working on finishing stuff and mixes.”

“It’s been a long time coming and I can’t wait for people to hear it.”

The release date has been put back a few times, but Robin now estimates it will be May.

“Whether we can actually hold to that I have no idea,” he says. “I’m trying my damnedest, but it will definitely be this summer. Definitely.”

“We’ve been writing while we’ve been on the road in the same way that we always do. We write the lyrics between us and we jam the music together as a band and that’s the same way we’re doing it this time around.”

“I’m really pleased with the album,” Robin says. “It’s very varied, it’s very different. It’s not one style, you know? It’s not a UB40 Labour of Love style, it’s not all poppy and commercial, there’s going to be lots of dub on it. It’s a mixture.”

On top of all this, the band has just entered its 40th year, having formed in 1978, famously taking their name from an Unemployment Benefit card.

“I can’t quite get my head round that really. When you start you hope for longevity and you think that if you get ten years out of it you’ll do well, but that’s longer than most bands’ careers.”

“I still can’t believe that this is what I do for a living,” he marvels. “I could have been stuck in a factory for all of my life but I’m still doing what I love doing.”

“I don’t know how long I can keep this up for, but as long as I’m loving it I’m going to keep going. It’s a wonderful way to spend your life and it’s great way to earn a living.”

Looking back, Robin is proud of the band’s success – almost 40 singles in the UK Top 40 charts and more than 70 million records sold worldwide.

But Robin’s also proud that they’re still going.

“The fact that we’ve done everything we’ve done, had the success that we’ve had, that’s all in the record books. That speaks for itself. But just the fact that we’re still doing it makes me immensely proud.”

Anyone who knows about the band’s difficult period a few years ago will understand that this is no small feat.

It all begs the question: what are the reasons for the band’s enduring appeal?

“Ooh, that’s not an original question,” Robin laughs. “I really haven’t got a clue what the secret is.”

“We are the sum of our parts and luckily we have a sound that’s original and that people love,” he says. “And we’ve got a very loyal fanbase. I don’t know how you get that.”

“You just have to keep doing what you do and do what you like and hope that your fans come with you.”

A Boundless Summer is presented by Boundless and Neil O’Brien Entertainment.
